 ## Goal
 
-Covers [mainPlan.md §12](./mainPlan.md#12-returns--claims-management) in
-full. [05_delivery_ride.md](./05_delivery_ride.md) and [09_fraud_controls.md](./09_fraud_controls.md)
-both reference this step's credit note and approval shapes — this is where those are actually
-defined.
+Covers [mainPlan.md §12](./mainPlan.md#12-returns--claims-management) — a customer-side flow where
+a sales rep records a return during a store visit and a claim workflow against a Regional Agency,
+plus a supplier-side flow for claims against a `PurchaseOrder`/`GoodsReceipt` that don't involve
+physically returning goods.
+
+### Four distinct entities — don't conflate them
+
+`SaleReturn` and `PurchaseReturn` are both named "...Return" but move goods in opposite
+directions, and neither is the same as the two `Claim` entities, which never move stock at all:
+
+| Entity | Direction | Where it lives | Approval? | Stock effect |
+|---|---|---|---|---|
+| `SaleReturn` | Shop → Distributor | This step (`Features/Returns`) | No — settles immediately | Credits the ride's **vehicle** |
+| `Claim` | vs. Regional Agency | This step (`Features/Claims`) | Settle only (`claims.settle`) | None |
+| `PurchaseReturn` | Distributor → Supplier | [15_procurement.md](./15_procurement.md) (`Features/PurchaseReturn`) | No — settles immediately | Debits the receiving **warehouse** |
+| `SupplierClaim` | vs. Supplier | This step (`Features/SupplierClaims`) | Yes (`suppliers.claims.approve`) | None — financial/administrative record only |
+
+`PurchaseReturn` is for physically shipping goods back to a supplier; `SupplierClaim` is for
+disputes that don't (or can't yet) involve moving goods back — a short-shipment, damage, or a
+price dispute.
 
 ---
 
 ## Background / Context
 
-No return, credit note, or claim entity exists today. `createBackorder` (§1,
-[05_delivery_ride.md](./05_delivery_ride.md)) needs a credit note target once this step lands.
+No return, credit note, or claim entity existed before this step. `createBackorder` (§1,
+[05_delivery_ride.md](./05_delivery_ride.md)) needed a credit note target once this step landed.
+
+The original spec (mainPlan §12) framed customer returns as an async, supervisor-approved
+workflow — `createReturnRequest` → `approveReturn` → stock credited only on approval. **That model
+was dropped during planning.** In practice a sales rep records a return on the spot, during the
+same store visit as a new order, and it must settle immediately (stock back in the vehicle, the
+new order's amount adjusted) — there is no point in the field workflow where a return sits
+"pending" a remote supervisor's sign-off. See Business Rules for what this changes.
+
+The existing `PurchaseReturn` ([15_procurement.md](./15_procurement.md)) only covers physically
+returning received goods to a supplier and debiting stock — it has no place for a claim that
+doesn't (or can't yet) involve moving goods back: a short-shipment (500 ordered, 480 received),
+goods damaged in transit, or a price dispute. `SupplierClaim` was added alongside `PurchaseReturn`
+for this, not as a rework of it.
+
+### Connections to existing modules
+
+- **Order Management**: a `SaleReturn` is always filed against a specific open `Order`
+  (`Features/Order`) and immediately nets its effect onto that order's `TotalAmount` /
+  `OrderItem.Quantity` — no `Invoice` entity exists yet (Finance, step 19, not built), so there is
+  nothing else for a credit note to net against.
+- **Stock Ledger** ([02_stock_ledger.md](./02_stock_ledger.md)): `SaleReturn` credits
+  `StockBalance` at the active ride's vehicle (`MovementType.CustomerReturn`), the same enum value
+  `StockService.RecordCustomerReturnAsync` already defined but that no sales-side flow was wiring
+  up until this step. `SupplierClaim` writes no stock movement at all (see Business Rules).
+- **Ride Execution** ([05_delivery_ride.md](./05_delivery_ride.md)): a `SaleReturn` can only be
+  recorded against an order created during an active ride (`Sale.FK_RideId` must be set), since
+  stock is credited back to that ride's vehicle (`DeliveryRun.FK_VehicleId`).
+- **Region Management** ([10_region_management.md](./10_region_management.md)): there is no
+  separate Agency entity in the codebase — "Regional Agency" is a `Role`
+  (`Data/Seed/RoleAndPermissionSeed.cs`), so `Claim` references the `User` holding that role.
+- **Procurement** ([15_procurement.md](./15_procurement.md)): `SupplierClaim.FK_PurchaseOrderId`
+  is required, `FK_GoodsReceiptId` optional; a short-shipment is already excluded from stock at
+  receipt time (`GoodsReceiptItem.RejectedQuantity`), so `SupplierClaim` never needs to touch
+  `StockBalance` itself.

+## Migrations
+
+Two migrations, applied:
+1. **AddReturnsAndClaims** (`20260825073453_AddReturnsAndClaims`) — created `SaleReturns`,
+   `SaleReturnItems`, `CreditNotes`, `Claims`, with FKs to `Orders`/`Items`/`Users` and indexes on
+   every FK column.
+2. **AddSupplierClaims** (`20260825084218_AddSupplierClaims`) — created `SupplierClaims`,
+   `SupplierClaimItems`, with FKs to `PurchaseOrders`/`GoodsReceipts`/`Items`/`Users` and indexes on
+   every FK column.
+
+Both applied via `dotnet ef database update`.

-| `generateCreditNote(returnId)` | `POST /api/returns/{id}/credit-note` — auto-triggered on approval |
-| `createClaim(agencyId, claimDetails)` | `POST /api/claims` |
-| `settleClaim(claimId, settlementAmount)` | `POST /api/claims/{id}/settle` |
+| `createSaleReturn(orderId, mode, items[])` | `POST /api/orders/{id}/returns` — creates and immediately settles |
+| `getSaleReturn(returnId)` | `GET /api/returns/{id}` |
+| `listSaleReturns(orderId)` | `GET /api/orders/{id}/returns` |
+
+### Claims (`Features/Claims`)
+| Function reference | Endpoint |
+|---|---|
+| `createClaim(agencyUserId, details)` | `POST /api/claims` |
+| `getClaim(claimId)` | `GET /api/claims/{id}` |
+| `settleClaim(claimId, settlementAmount)` | `POST /api/claims/{id}/settle` — `[Authorize(Policy = "claims.settle")]` |
+
+### Supplier Claims (`Features/SupplierClaims`)
+| Function reference | Endpoint |
+|---|---|
+| `createSupplierClaim(poId, grnId?, items[], details, evidenceUrl?)` | `POST /api/purchase-orders/{id}/claims` |
+| `getSupplierClaim(claimId)` | `GET /api/supplier-claims/{id}` |
+| `listSupplierClaims(poId)` | `GET /api/purchase-orders/{id}/claims` |

+| `rejectSupplierClaim(claimId, notes?)` | `POST /api/supplier-claims/{id}/reject` — `[Authorize(Policy = "suppliers.claims.approve")]` |
+
+`approve`/`reject` combine the "inspect the claim" and "decide the outcome" steps into one call —
+unlike the customer-side flow there's no separate physical-inspection step to wait on here, since
+the evidence (photos/notes, and `GoodsReceiptItem.RejectedQuantity` if applicable) is already
+attached at claim-creation time.

 ## Business Rules
 
-- `approveReturn` requires supervisor sign-off before stock is credited back — matches the rule
-  already stated in [09_fraud_controls.md](./09_fraud_controls.md).
-- A `Return Request` must reference a real prior sale/delivery line — the absence of one is exactly
-  the `ReturnWithoutSale` anomaly flagged automatically in
-  [09_fraud_controls.md](./09_fraud_controls.md).
-- Approving a return creates a `Return` stock movement crediting the relevant location, per
-  [02_stock_ledger.md](./02_stock_ledger.md).
+1. `createSaleReturn` is the entry point — no prior approval step, settlement is immediate. This
+   deliberately supersedes the original spec's `Pending → Approved/Rejected` flow (see
+   Background/Context) since a rep records the return on the spot during a live store visit.
+2. A return can only be filed against an order that is still open (`OrderStatus.Pending` or
+   `PartiallyFulfilled`) — not `Fulfilled`/`Cancelled` — and whose `Sale.FK_RideId` is set, since
+   stock is credited back to that ride's vehicle (`DeliveryRun.FK_VehicleId`,
+   `MovementType.CustomerReturn`).
+3. `createSaleReturn` rejects (409 Conflict) any line item the store has never had on **any** of
+   its past orders — checked across the store's full order history, not just the order the return
+   is filed against. This lets an expired or damaged item bought weeks ago still be returned; it
+   only blocks an item that store never bought at all — the real fraud case originally scoped as
+   `ReturnWithoutSale` in [09_fraud_controls.md](./09_fraud_controls.md), which is not otherwise
+   built.
+4. `Mode = CreditDeduction`: the returned lines' value (`Quantity * UnitPrice`) is subtracted from
+   `Order.TotalAmount` (floored at 0), and a `CreditNote` audit row is written.
+5. `Mode = ItemExchange`: the returned quantity is subtracted directly from the matching
+   `OrderItem.Quantity` on the same order (a physical swap of the same item), `TotalAmount`
+   adjusted by the offset amount. No `CreditNote` is written. A returned item with no matching line
+   on the order is credited to stock but does not offset anything on the order.
+6. Stock credit, the `SaleReturn`/`SaleReturnItem` insert, and the order-total/credit-note update
+   all run inside one `IUnitOfWork` transaction — a failure anywhere rolls back the whole return.
+7. `settleClaim` can only run once per claim — rejects (409) if already `Settled`. Claims never
+   touch `StockBalance` or any `Order`.
+8. `createSupplierClaim` requires the referenced `PurchaseOrder` to exist and be active;
+   `FK_GoodsReceiptId`, if given, must belong to that PO (rejects with 409 otherwise).
+9. Only `Open` supplier claims can be approved or rejected; both are terminal (no re-opening) —
+   enforced by `ApproveAsync`/`RejectAsync` throwing if `Status != Open`.
+10. `approveSupplierClaim` requires `ResolutionType`; `ResolutionAmount` is required for `Credit`,
+    `Refund`, and `PriceAdjustment` (409 if missing), and is discarded (`null`) for `Replacement`
+    even if supplied.
+11. Supplier claim approval/rejection is a real sign-off step (unlike the customer-side
+    `SaleReturn`, which settles immediately) — gated behind
+    `[Authorize(Policy = "suppliers.claims.approve")]`, following the Ride cancel-request pattern
+    (`RideController.cs:120-146`).
+12. No automatic `StockBalance`/`StockMovement` write from any `SupplierClaim` action.
+    `ResolutionType = Replacement` records that new stock is expected; the actual stock credit
+    happens through an ordinary follow-up `GoodsReceipt` once it arrives (see Open Questions).
+    `Credit`/`Refund`/`PriceAdjustment` have no `Invoice`/Finance ledger to post against yet
+    (step 19, not built) — `ResolutionAmount` is captured as an audit field only, the same
+    limitation `CreditNote` has on the customer side.
+
+---
+
+## Permissions to Add to Seed
+
+**Status: `claims.settle` and `suppliers.claims.approve` enforced; return-creation routes
+intentionally left as bare `[Authorize]`**, matching the Supplier/PriceList/Procurement convention
+(steps 14/15) rather than introducing enforcement piecemeal. Both enforced policies use the same
+dynamic policy-provider pattern as `rides.cancel.approve` (`PermissionPolicyProvider`) — no
+explicit policy registration needed, just a seeded `Permission` row and a `RolePermission` grant.
+No role assignments seeded yet; `suppliers.claims.approve` likely AreaManager (30) and above,
+matching the Supplier/Procurement tier.
 
 ---
 
 ## Open Questions
 
+- Should return-creation routes eventually get a real permission policy (`returns.create`) once
+  the Supplier/PriceList/Procurement group does, or do they stay bare `[Authorize]` indefinitely
+  since a rep needs to record a return without waiting on a scoped grant?
+- `ItemExchange` mode clamps the offset to `min(returnedQty, orderItem.Quantity)` — if a rep
+  returns more of an item than is on the current order, the excess is credited to stock but not
+  reflected anywhere on the order. Worth a `CreditNote`-style fallback for the excess once this
+  edge case actually comes up.
+- No `Invoice` entity exists yet (Finance, step 19) — `CreditNote` and `SupplierClaim`'s
+  `ResolutionAmount` are standalone audit fields for now, not linked to any invoice/ledger
+  document. Revisit once Finance & Accounting is built.
 - Are `Claim`s only against Regional Agencies (as the reference doc frames them), or can a claim

+# Authentication — Own-User Auth via External Identity Service (AuthHex)
+
+**Status**: Done
+**Depends On**: — (cross-cutting infrastructure, not a numbered feature step)
+
+---
+
+## Goal
+
+Own-user (staff/API) authentication is delegated to an external identity service ("AuthHex"),
+which owns credentials and signs RS256 JWTs. This app validates those tokens and maps them onto
+its own `User`/`Role` tables so the existing permission-policy authorization stays unchanged.
+
+---
+
+## Background / Context
+
+Previously this app verified passwords and minted its own HMAC-signed JWT locally. That's been
+replaced — AuthHex now owns credentials and signing; this app only holds AuthHex's **public** key
+to validate tokens, and never sees a plaintext password for this flow.
+
+Authorization is untouched: permission policies, role levels, scope checks, and the seeded role
+set all still work exactly as before, because every validated token is mapped back onto a local
+`User`/`Role` row before any authorization check runs.
+
+---
+
+## Configuration Changes
+
+```jsonc
+"Jwt": {
+  "PublicKey": "<RSAKeyValue>...</RSAKeyValue>",
+  "Audience": "AuthHexClient",
+  "Issuer": "AuthHex"
+},
+"AuthHex": { "BaseUrl": "http://localhost:6102" }
+```
+
+`Jwt:Key` (old symmetric secret) is removed. `Jwt:PublicKey` is AuthHex's RSA public key in XML
+format (not PEM).
+
+---
+
+## API Endpoints
+
+| Method | Route | Notes |
+|---|---|---|
+| POST | /api/auth/login | Proxies to AuthHex `loginUser` |
+| POST | /api/auth/register | Proxies to AuthHex `registerUser` |
+| GET | /api/auth/me | `[Authorize]`, proxies to AuthHex `getUserDetails` |
+| POST | /api/auth/logout | `[Authorize]`, proxies to AuthHex `LogoutUser` |
+
+All four just forward to `POST {AuthHex:BaseUrl}/api/user` and pass AuthHex's response back
+as-is. No cookie — token returned in the response body, sent back as `Authorization: Bearer`.
+
+---
+
+## Business Rules
+
+1. No local password check or token issuance — both delegated to AuthHex.
+2. `AddJwtBearer` validates issuer/audience/signature/lifetime against AuthHex's public key.
+3. `OnTokenValidated` maps the token's `sub` claim to a local `User` (`IUserRepository`); fails
+   the token if no matching active user exists.
+4. On success, `username`/`role_id`/`role_level` claims are attached from the **local** `User`/
+   `Role` row — authorization checks downstream are unaffected by anything AuthHex's own token
+   claims contain.
+5. Only one validation mechanism runs (`AddJwtBearer`) — two ported alternatives exist but are not
+   registered (see Implementation Notes).
+6. No refresh tokens — once the AuthHex-issued token expires, the client must log in again.
+
+---
+
+## Permissions to Add to Seed
+
+None — this only changes authentication. Permission policies and role seed data are untouched.
+
+---
+
+## Open Questions
+
+- Add a refresh-token flow if AuthHex doesn't offer one and re-login UX proves disruptive.
+- Keep or delete the ported `AuthMiddleware`/`JwtMiddleware` if never actually needed.
+- No retry/circuit-breaker if AuthHex is unreachable.
+
+---
+
+## Implementation Notes
+
+```
+Features/Auth/            — AuthController, AuthService, AuthDTOs (thin AuthHex proxies)
+Infra/Authorization/
+  AuthHex/                 — IAuthHexClient, AuthHexClient, AuthHexResponse
+  Jwt/RsaXmlKeyReader.cs    — portable XML→RSA key parser (RSA.FromXmlString is Windows-only)

+                               (maps token → local User/Role → role_id/role_level claims)
+```
+
+**Gotcha:** don't run more than one of `AddJwtBearer` / `AuthMiddleware` /
+`JwtMiddleware.CustomMiddlewareAttribute` at once — each re-validates the same token
+independently.

 ### 1. Order Management
 
+> **Design change since this section was first written**: `Order` is no longer created directly
+> from `storeId/items/salesRepId`. Order creation was folded into `Features/Sale` — every `Order`
+> is now a 1:1 side effect of `SaleService.CreateAsync` (see §6 Sale Ride Execution). `POST
+> /api/orders` (`OrderService.CreateAsync`) is now just a lookup — it throws
+> `"Orders are created automatically from sales"` if called for a sale that doesn't already have
+> one, rather than creating a standalone order. All the validation described below (stock check,
+> KYC threshold, pricing) now happens in `SaleService.CreateAsync`
+> (`Features/Sale/SaleService.cs`), not `OrderService`.
+
 | Function | What it does | Status |
 |---|---|---|
-| `createOrder(storeId, items[], salesRepId)` | Validates stock/credit, creates a new order in `pending` state. | Partially implemented - `OrderService.CreateAsync` exists, enforces store scope, blocks inactive stores, applies the unverified-KYC order threshold from config, and now checks stock availability (see `checkStockAvailability` below). It still has no credit-limit validation, approval flow, or order state machine. |
-| `validateCreditLimit(storeId, orderAmount)` | Checks store's outstanding balance + new order value against its credit limit. | Not implemented - `Store` now has `CreditLimit` and `OutstandingBalance`, but there is no dedicated validator or order-time credit-limit enforcement yet. |
-| `checkStockAvailability(items[])` | Confirms requested SKUs/quantities are available at the fulfilling warehouse. | Implemented — `OrderService.CreateAsync` rejects an order if any line's requested quantity exceeds total `StockBalance` for that item summed across every location (added alongside [15_procurement.md](./15_procurement.md)). Not location-specific yet (no fulfilling-warehouse concept on `Store`/`Order`), and does not reserve or decrement stock — that stays deferred to loading/delivery (§05-06). |
-| `applyPricingAndDiscounts(orderId)` | Runs the active price list and eligible scheme rules against order lines. | Partially implemented — `OrderService.CreateAsync` resolves the price-list half via `PriceListService.ResolveUnitPriceAsync` (region-scoped → global → `Item.SalePrice`, or a caller-supplied `UnitPrice`). The scheme-discount half now exists as a separate call — `SchemeService.EvaluateEligibilityAsync`/`ApplySchemeAsync` (§11) — but is not yet auto-invoked from `OrderService.CreateAsync`; the caller applies a scheme explicitly via `POST /api/orders/{id}/apply-scheme` after order creation. |
+| `createOrder(storeId, items[], salesRepId)` | Validates stock/credit, creates a new order in `pending` state. | Superseded — see design-change note above. The equivalent entry point is `SaleService.CreateAsync` (`createSale`, §6), which creates the `Sale` and its linked `Order` together. `OrderService.CreateAsync` itself only fetches the existing order for a given `SaleId`. |
+| `validateCreditLimit(storeId, orderAmount)` | Checks store's outstanding balance + new order value against its credit limit. | Not implemented - `Store` has `CreditLimit` and `OutstandingBalance`, but there is no dedicated validator or sale/order-time credit-limit enforcement yet. |
+| `checkStockAvailability(items[])` | Confirms requested SKUs/quantities are available at the fulfilling warehouse. | Partially implemented — `SaleService.CreateAsync` checks `StockBalance` at the ride's vehicle, but **only** when `FulfillImmediately = true` and a `RideId` is supplied (immediate van-sale handover); a deferred/pending sale does no stock check at create time at all. Not warehouse-wide, not reserved — a failed check simply returns `null` (400) rather than a typed error. |
+| `applyPricingAndDiscounts(orderId)` | Runs the active price list and eligible scheme rules against order lines. | Partially implemented — `SaleService.CreateAsync` resolves the price-list half via `ResolveUnitPriceAsync` → `PriceListService.ResolvePriceAsync` (region-scoped via the store's route → `Item.SalePrice` fallback, or a caller-supplied `UnitPrice` validated against `[MinPrice, Price]`). The scheme-discount half is a separate call — `SchemeService.EvaluateEligibilityAsync`/`ApplySchemeAsync` (§11) — not auto-invoked from `createSale`; the caller applies a scheme explicitly via `POST /api/orders/{id}/apply-scheme` after the order exists. |
 | `submitOrderForApproval(orderId)` | Routes the order to the correct approver based on its value/discount threshold. | Not implemented — depends on [08_sales_agent_controls.md](./08_sales_agent_controls.md). |

-| `updateOrderStatus(orderId, status)` | Transitions order through `pending → approved → picked → dispatched → delivered → invoiced`. | Not implemented — `Order` has no status field or state machine today. |
+| `updateOrderStatus(orderId, status)` | Transitions order through `pending → approved → picked → dispatched → delivered → invoiced`. | Implemented, with a smaller state machine than described — `Models/Enums.cs` defines `OrderStatus { Pending, PartiallyFulfilled, Fulfilled, Cancelled }`; `OrderService.UpdateAsync` (`PUT /api/orders/{id}`) sets `Order.Status` directly (any status accepted, no transition guard) and mirrors it onto the linked `Sale.Status`/`CompletedAt`. No `approved/picked/dispatched/invoiced` states exist. |
 | `convertOrderToInvoice(orderId)` | Generates the invoice once the order is dispatched/delivered. | Not implemented — depends on §13 Finance & Accounting. |
 | `createBackorder(orderId, unfulfilledItems[])` | Splits unfulfillable quantity into a linked backorder. | Not implemented. |

+
+# shadcn/ui
+
+A framework for building ui, components and design systems. Components are added as source code to the user's project via the CLI.
+
+> **IMPORTANT:** Run all CLI commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest` — based on the project's `packageManager`. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
+
+## Current Project Context
+
+```json
+!`npx shadcn@latest info --json`
+```
+
+The JSON above contains the project config and installed components. Use `npx shadcn@latest docs <component>` to get documentation and example URLs for any component.
+
+## Principles
+
+1. **Use existing components first.** Use `npx shadcn@latest search` to check registries before writing custom UI. Check community registries too.
+2. **Compose, don't reinvent.** Settings page = Tabs + Card + form controls. Dashboard = Sidebar + Card + Chart + Table.
+3. **Use built-in variants before custom styles.** `variant="outline"`, `size="sm"`, etc.
+4. **Use semantic colors.** `bg-primary`, `text-muted-foreground` — never raw values like `bg-blue-500`.
+
+## Critical Rules
+
+These rules are **always enforced**. Each links to a file with Incorrect/Correct code pairs.
+
+### Styling & Tailwind → [styling.md](./rules/styling.md)
+
+- **`className` for layout, not styling.** Never override component colors or typography.
+- **No `space-x-*` or `space-y-*`.** Use `flex` with `gap-*`. For vertical stacks, `flex flex-col gap-*`.
+- **Use `size-*` when width and height are equal.** `size-10` not `w-10 h-10`.
+- **Use `truncate` shorthand.** Not `overflow-hidden text-ellipsis whitespace-nowrap`.
+- **No manual `dark:` color overrides.** Use semantic tokens (`bg-background`, `text-muted-foreground`).
+- **Use `cn()` for conditional classes.** Don't write manual template literal ternaries.
+- **No manual `z-index` on overlay components.** Dialog, Sheet, Popover, etc. handle their own stacking.
+
+### Forms & Inputs → [forms.md](./rules/forms.md)
+
+- **Forms use `FieldGroup` + `Field`.** Never use raw `div` with `space-y-*` or `grid gap-*` for form layout.
+- **`InputGroup` uses `InputGroupInput`/`InputGroupTextarea`.** Never raw `Input`/`Textarea` inside `InputGroup`.
+- **Buttons inside inputs use `InputGroup` + `InputGroupAddon`.**
+- **Option sets (2–7 choices) use `ToggleGroup`.** Don't loop `Button` with manual active state.
+- **`FieldSet` + `FieldLegend` for grouping related checkboxes/radios.** Don't use a `div` with a heading.
+- **Field validation uses `data-invalid` + `aria-invalid`.** `data-invalid` on `Field`, `aria-invalid` on the control. For disabled: `data-disabled` on `Field`, `disabled` on the control.
+
+### Component Structure → [composition.md](./rules/composition.md)
+
+- **Items always inside their Group.** `SelectItem` → `SelectGroup`. `DropdownMenuItem` → `DropdownMenuGroup`. `CommandItem` → `CommandGroup`.
+- **Use `asChild` (radix) or `render` (base) for custom triggers.** Check `base` field from `npx shadcn@latest info`. → [base-vs-radix.md](./rules/base-vs-radix.md)
+- **Dialog, Sheet, and Drawer always need a Title.** `DialogTitle`, `SheetTitle`, `DrawerTitle` required for accessibility. Use `className="sr-only"` if visually hidden.
+- **Use full Card composition.** `CardHeader`/`CardTitle`/`CardDescription`/`CardContent`/`CardFooter`. Don't dump everything in `CardContent`.
+- **Button has no `isPending`/`isLoading`.** Compose with `Spinner` + `data-icon` + `disabled`.
+- **`TabsTrigger` must be inside `TabsList`.** Never render triggers directly in `Tabs`.
+- **`Avatar` always needs `AvatarFallback`.** For when the image fails to load.
+
+### Use Components, Not Custom Markup → [composition.md](./rules/composition.md)
+
+- **Use existing components before custom markup.** Check if a component exists before writing a styled `div`.
+- **Callouts use `Alert`.** Don't build custom styled divs.
+- **Empty states use `Empty`.** Don't build custom empty state markup.
+- **Toast follows the project base.** Use `toast` from the `toast` component for
+  Base UI projects. Use `toast()` from `sonner` for Radix and React Aria
+  projects.
+- **Use `Separator`** instead of `<hr>` or `<div className="border-t">`.
+- **Use `Skeleton`** for loading placeholders. No custom `animate-pulse` divs.
+- **Use `Badge`** instead of custom styled spans.
+
+### Icons → [icons.md](./rules/icons.md)
+
+- **Icons in `Button` use `data-icon`.** `data-icon="inline-start"` or `data-icon="inline-end"` on the icon.
+- **No sizing classes on icons inside components.** Components handle icon sizing via CSS. No `size-4` or `w-4 h-4`.
+- **Pass icons as objects, not string keys.** `icon={CheckIcon}`, not a string lookup.
+
+### Chat & Messaging → [chat.md](./rules/chat.md)
+
+- **Chat UI composes the chat primitives.** Conversations use `MessageScroller`, rows use `Message`, surfaces use `Bubble`. Never hand-rolled bubble `div`s or a raw scroll container.
+- **`MessageScroller` owns scroll behavior.** Streaming follow, anchoring, and jump-to-latest (`MessageScrollerButton`) are built in. Don't write a `useStickToBottom`/`ResizeObserver` hook.
+- **Attachments use `Attachment`; system notes and dividers use `Marker`.** Not `Item` cards or `Separator` + a label.
+
+### CLI
+
+- **Never decode preset codes or build preset URLs manually.** Use `npx shadcn@latest preset decode <code>`, `preset url <code>`, or `preset open <code>`. For project-aware preset detection, use `npx shadcn@latest preset resolve`.
+- **Apply preset codes directly with the CLI.** Use `npx shadcn@latest apply <code>` for existing projects, or `npx shadcn@latest init --preset <code>` when initializing.
+
+## Key Patterns
+
+These are the most common patterns that differentiate correct shadcn/ui code. For edge cases, see the linked rule files above.
+
+```tsx
+// Form layout: FieldGroup + Field, not div + Label.
+<FieldGroup>
+  <Field>
+    <FieldLabel htmlFor="email">Email</FieldLabel>
+    <Input id="email" />
+  </Field>
+</FieldGroup>
+
+// Validation: data-invalid on Field, aria-invalid on the control.
+<Field data-invalid>
+  <FieldLabel>Email</FieldLabel>
+  <Input aria-invalid />
+  <FieldDescription>Invalid email.</FieldDescription>
+</Field>
+
+// Icons in buttons: data-icon, no sizing classes.
+<Button>
+  <SearchIcon data-icon="inline-start" />
+  Search
+</Button>
+
+// Spacing: gap-*, not space-y-*.
+<div className="flex flex-col gap-4">  // correct
+<div className="space-y-4">           // wrong
+
+// Equal dimensions: size-*, not w-* h-*.
+<Avatar className="size-10">   // correct
+<Avatar className="w-10 h-10"> // wrong
+
+// Status colors: Badge variants or semantic tokens, not raw colors.
+<Badge variant="secondary">+20.1%</Badge>    // correct
+<span className="text-emerald-600">+20.1%</span> // wrong
+```

+
+## Key Fields
+
+The injected project context contains these key fields:
+
+- **`aliases`** → use the actual alias prefix for imports (e.g. `@/`, `~/`), never hardcode.
+- **`isRSC`** → when `true`, components using `useState`, `useEffect`, event handlers, or browser APIs need `"use client"` at the top of the file. Always reference this field when advising on the directive.
+- **`tailwindVersion`** → `"v4"` uses `@theme inline` blocks; `"v3"` uses `tailwind.config.js`.
+- **`tailwindCssFile`** → the global CSS file where custom CSS variables are defined. Always edit this file, never create a new one.
+- **`style`** → component visual treatment (e.g. `nova`, `vega`).
+- **`base`** → primitive library (`radix` or `base`). Affects component APIs and available props.
+- **`iconLibrary`** → determines icon imports. Use `lucide-react` for `lucide`, `@tabler/icons-react` for `tabler`, etc. Never assume `lucide-react`.
+- **`resolvedPaths`** → exact file-system destinations for components, utils, hooks, etc.
+- **`framework`** → routing and file conventions (e.g. Next.js App Router vs Vite SPA).
+- **`packageManager`** → use this for any non-shadcn dependency installs (e.g. `pnpm add date-fns` vs `npm install date-fns`).
+- **`preset`** → resolved preset code and values for the current project. Use `npx shadcn@latest preset resolve --json` when you only need preset information.
+
+See [cli.md — `info` command](./cli.md) for the full field reference.
+
+## Component Docs, Examples, and Usage
+
+Run `npx shadcn@latest docs <component>` to get the URLs for a component's documentation, examples, and API reference. Fetch these URLs to get the actual content.
+
+```bash
+npx shadcn@latest docs button dialog select
+```
+
+**When creating, fixing, debugging, or using a component, always run `npx shadcn@latest docs` and fetch the URLs first.** This ensures you're working with the correct API and usage patterns rather than guessing.
+
+## Workflow
+
+1. **Get project context** — already injected above. Run `npx shadcn@latest info` again if you need to refresh.
+2. **Check installed components first** — before running `add`, always check the `components` list from project context or list the `resolvedPaths.ui` directory. Don't import components that haven't been added, and don't re-add ones already installed.
+3. **Find components** — `npx shadcn@latest search`.
+4. **Get docs and examples** — run `npx shadcn@latest docs <component>` to get URLs, then fetch them. Use `npx shadcn@latest view` to browse registry items you haven't installed. To preview changes to installed components, use `npx shadcn@latest add --diff`.
+5. **Install or update** — `npx shadcn@latest add`. When updating existing components, use `--dry-run` and `--diff` to preview changes first (see [Updating Components](#updating-components) below).
+6. **Fix imports in third-party components** — After adding components from community registries (e.g. `@bundui`, `@magicui`), check the added non-UI files for hardcoded import paths like `@/components/ui/...`. These won't match the project's actual aliases. Use `npx shadcn@latest info` to get the correct `ui` alias (e.g. `@workspace/ui/components`) and rewrite the imports accordingly. The CLI rewrites imports for its own UI files, but third-party registry components may use default paths that don't match the project.
+7. **Review added components** — After adding a component or block from any registry, **always read the added files and verify they are correct**. Check for missing sub-components (e.g. `SelectItem` without `SelectGroup`), missing imports, incorrect composition, or violations of the [Critical Rules](#critical-rules). Also replace any icon imports with the project's `iconLibrary` from the project context (e.g. if the registry item uses `lucide-react` but the project uses `hugeicons`, swap the imports and icon names accordingly). Fix all issues before moving on.
+8. **Registry must be explicit** — When the user asks to add a block or component, **do not guess the registry**. If no registry is specified (e.g. user says "add a login block" without specifying `@shadcn`, `@tailark`, `owner/repo`, etc.), ask which registry to use. Never default to a registry on behalf of the user.
+9. **Switching presets** — Ask the user first: **overwrite**, **partial**, **merge**, or **skip**?
+   - **Inspect current preset**: `npx shadcn@latest preset resolve`. Use `--json` when you need structured values.
+   - **Inspect incoming preset**: `npx shadcn@latest preset decode <code>`. Use `preset url <code>` or `preset open <code>` to share or open the preset builder.
+   - **Overwrite**: `npx shadcn@latest apply <code>`. Overwrites detected components, fonts, and CSS variables.
+   - **Partial**: `npx shadcn@latest apply <code> --only theme,font`. Updates only the selected preset parts without reinstalling UI components. Supported values are `theme` and `font`; comma-separated combinations are allowed. `icon` is intentionally not supported, because icon changes may require full component reinstall and transforms.
+   - **Merge**: `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to list installed components, then for each installed component use `--dry-run` and `--diff` to [smart merge](#updating-components) it individually.
+   - **Skip**: `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS, leaves components as-is.
+   - **Important**: Always run preset commands inside the user's project directory. `apply` only works in an existing project with a `components.json` file. The CLI automatically preserves the current base (`base` vs `radix`) from `components.json`. If you must use a scratch/temp directory (e.g. for `--dry-run` comparisons), pass `--base <current-base>` explicitly — preset codes do not encode the base.
+
+## Updating Components
+
+When the user asks to update a component from upstream while keeping their local changes, use `--dry-run` and `--diff` to intelligently merge. **NEVER fetch raw files from GitHub manually — always use the CLI.**
+
+1. Run `npx shadcn@latest add <component> --dry-run` to see all files that would be affected.
+2. For each file, run `npx shadcn@latest add <component> --diff <file>` to see what changed upstream vs local.
+3. Decide per file based on the diff:
+   - No local changes → safe to overwrite.
+   - Has local changes → read the local file, analyze the diff, and apply upstream updates while preserving local modifications.
+   - User says "just update everything" → use `--overwrite`, but confirm first.
+4. **Never use `--overwrite` without the user's explicit approval.**

+# shadcn CLI Reference
+
+Configuration is read from `components.json`.
+
+> **IMPORTANT:** Always run commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest`. Check `packageManager` from project context to choose the right one. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
+
+> **IMPORTANT:** Only use the flags documented below. Do not invent or guess flags — if a flag isn't listed here, it doesn't exist. The CLI auto-detects the package manager from the project's lockfile; there is no `--package-manager` flag.

+## Commands
+
+### `init` — Initialize or create a project
+
+```bash
+npx shadcn@latest init [components...] [options]
+```
+
+Initializes shadcn/ui in an existing project or creates a new project (when `--name` is provided). Optionally installs components in the same step.

+
+`npx shadcn@latest create` is an alias for `npx shadcn@latest init`.
+
+### `apply` — Apply a preset to an existing project
+
+```bash
+npx shadcn@latest apply [preset] [options]
+```
+
+Applies a preset to an existing project, overwriting preset-driven config, fonts, CSS variables, and detected UI components.
+
+| Flag                | Short | Description                                | Default |
+| ------------------- | ----- | ------------------------------------------ | ------- |
+| `--preset <preset>` | —     | Preset configuration (named, code, or URL) | —       |
+| `--yes`             | `-y`  | Skip confirmation prompt                   | `false` |
+| `--cwd <cwd>`       | `-c`  | Working directory                          | current |
+| `--silent`          | `-s`  | Mute output                                | `false` |
+
+`[preset]` is a shorthand for `--preset <preset>`. If both are provided, they must match.
+If no preset is provided, the CLI offers to open the custom preset builder on `ui.shadcn.com/create`.
+
+### `add` — Add components
+
+> **IMPORTANT:** To compare local components against upstream or to preview changes, ALWAYS use `npx shadcn@latest add <component> --dry-run`, `--diff`, or `--view`. NEVER fetch raw files from GitHub or other sources manually. The CLI handles registry resolution, file paths, and CSS diffing automatically.
+
+```bash
+npx shadcn@latest add [components...] [options]
+```
+
+Accepts component names, registry-prefixed names (`@magicui/shimmer-button`),
+GitHub item addresses (`owner/repo/item`), URLs, or local paths.
+
+| Flag            | Short | Description                                                                                                          | Default |
+| --------------- | ----- | -------------------------------------------------------------------------------------------------------------------- | ------- |
+| `--yes`         | `-y`  | Skip confirmation prompt                                                                                             | `false` |
+| `--overwrite`   | `-o`  | Overwrite existing files                                                                                             | `false` |
+| `--cwd <cwd>`   | `-c`  | Working directory                                                                                                    | current |
+| `--all`         | `-a`  | Add all available components                                                                                         | `false` |

+| `--silent`      | `-s`  | Mute output                                                                                                          | `false` |
+| `--dry-run`     |       | Preview all changes without writing files                                                                            | `false` |
+| `--diff [path]` |       | Show diffs. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`)         | —       |
+| `--view [path]` |       | Show file contents. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`) | —       |
+
+#### Dry-Run Mode
+
+Use `--dry-run` to preview what `add` would do without writing any files. `--diff` and `--view` both imply `--dry-run`.
+
+```bash
+# Preview all changes.
+npx shadcn@latest add button --dry-run
+
+# Show diffs for all files (top 5).
+npx shadcn@latest add button --diff
+
+# Show the diff for a specific file.
+npx shadcn@latest add button --diff button.tsx
+
+# Show contents for all files (top 5).
+npx shadcn@latest add button --view
+
+# Show the full content of a specific file.
+npx shadcn@latest add button --view button.tsx
+
+# Works with URLs too.
+npx shadcn@latest add https://api.npoint.io/abc123 --dry-run
+
+# Works with public GitHub registries too.
+npx shadcn@latest add owner/repo/item --dry-run
+
+# CSS diffs.
+npx shadcn@latest add button --diff globals.css
+```
+
+**When to use dry-run:**
+
+- When the user asks "what files will this add?" or "what will this change?" — use `--dry-run`.
+- Before overwriting existing components — use `--diff` to preview the changes first.
+- When the user wants to inspect component source code without installing — use `--view`.
+- When checking what CSS changes would be made to `globals.css` — use `--diff globals.css`.
+- When the user asks to review or audit third-party registry code before installing — use `--view` to inspect the source.
+
+> **`npx shadcn@latest add --dry-run` vs `npx shadcn@latest view`:** Prefer `npx shadcn@latest add --dry-run/--diff/--view` over `npx shadcn@latest view` when the user wants to preview changes to their project. `npx shadcn@latest view` only shows raw registry metadata. `npx shadcn@latest add --dry-run` shows exactly what would happen in the user's project: resolved file paths, diffs against existing files, and CSS updates. Use `npx shadcn@latest view` only when the user wants to browse registry info without a project context.

+
+### `search` — Search registries
+
+```bash
+npx shadcn@latest search [registries...] [options]
+```
+
+Fuzzy search across registries. Also aliased as `npx shadcn@latest list`.
+Supports namespaces (`@acme`), public GitHub registry sources (`owner/repo`),
+and registry catalog URLs. Without `-q`, lists all items. When no registries are
+passed, searches every registry configured in `components.json`.
+
+| Flag                | Short | Description                                       | Default |
+| ------------------- | ----- | ------------------------------------------------- | ------- |
+| `--query <query>`   | `-q`  | Search query                                      | —       |
+| `--type <type>`     | `-t`  | Filter by item type (e.g. `ui`, `block`, `hook`); comma-separated | —       |
+| `--limit <number>`  | `-l`  | Max items to display                              | `100`   |
+| `--offset <number>` | `-o`  | Items to skip                                     | `0`     |
+| `--json`            |       | Output as JSON                                    | `false` |
+| `--cwd <cwd>`       | `-c`  | Working directory                                 | current |
+
+### `view` — View item details
+
+```bash
+npx shadcn@latest view <items...> [options]
+```
+
+Displays item info including file contents. Examples:
+`npx shadcn@latest view @shadcn/button`,
+`npx shadcn@latest view owner/repo/item`.
+
+### `docs` — Get component documentation URLs
+
+```bash
+npx shadcn@latest docs <components...> [options]
+```
+
+Outputs resolved URLs for component documentation, examples, and API references. Accepts one or more component names. Fetch the URLs to get the actual content.
+
+Example output for `npx shadcn@latest docs input button`:
+
+```
+base  radix
+
+input
+  docs      https://ui.shadcn.com/docs/components/radix/input
+  examples  https://raw.githubusercontent.com/.../examples/input-example.tsx
+
+button
+  docs      https://ui.shadcn.com/docs/components/radix/button
+  examples  https://raw.githubusercontent.com/.../examples/button-example.tsx
+```
+
+Some components include an `api` link to the underlying library (e.g. `cmdk` for the command component).
+
+### `diff` — Check for updates
+
+Do not use this command. Use `npx shadcn@latest add --diff` instead.
+
+### `info` — Project information
+
+```bash
+npx shadcn@latest info [options]
+```
+
+Displays project info and `components.json` configuration. Run this first to discover the project's framework, aliases, Tailwind version, and resolved paths.

+
+### `build` — Build a custom registry
+
+```bash
+npx shadcn@latest build [registry] [options]
+```
+
+Builds `registry.json` into individual JSON files for distribution. Default input: `./registry.json`, default output: `./public/r`.
+
+For authoring rules, `include`, item definitions, `registryDependencies`, and
+GitHub registry behavior, see [registry.md](./registry.md).

+## Templates
+
+| Value          | Framework      | Monorepo support |
+| -------------- | -------------- | ---------------- |
+| `next`         | Next.js        | Yes              |
+| `vite`         | Vite           | Yes              |
+| `start`        | TanStack Start | Yes              |
+| `react-router` | React Router   | Yes              |
+| `astro`        | Astro          | Yes              |
+| `laravel`      | Laravel        | No               |
+
+All templates support monorepo scaffolding via the `--monorepo` flag. When passed, the CLI uses a monorepo-specific template directory (e.g. `next-monorepo`, `vite-monorepo`). When neither `--monorepo` nor `--no-monorepo` is passed, the CLI prompts interactively. Laravel does not support monorepo scaffolding.

+
+## Presets
+
+Three ways to specify a preset via `--preset`:
+
+1. **Named:** `--preset nova` or `--preset lyra`
+2. **Code:** `--preset a2r6bw` (version-prefixed base62 string, e.g. `a2r6bw` or `b0`)
+3. **URL:** `--preset "https://ui.shadcn.com/init?base=radix&style=nova&..."`
+
+> **IMPORTANT:** Never try to decode, fetch, or resolve preset codes manually. Preset codes are opaque — pass them directly to `npx shadcn@latest init --preset <code>` and let the CLI handle resolution.
+> Use `npx shadcn@latest apply --preset <code>` when overwriting an existing project's preset.
+
+## Switching Presets
+
+Ask the user first: **overwrite**, **merge**, or **skip** existing components?
+
+- **Overwrite / Re-install** → `npx shadcn@latest apply --preset <code>`. Overwrites all detected component files with the new preset styles. Use when the user hasn't customized components.
+- **Merge** → `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to get the list of installed components and use the [smart merge workflow](./SKILL.md#updating-components) to update them one by one, preserving local changes. Use when the user has customized components.
+- **Skip** → `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS variables, leaves existing components as-is.
+
+Always run preset commands inside the user's project directory. `apply` only works in an existing project with a `components.json` file. The CLI automatically preserves the current base (`base` vs `radix`) from `components.json`. If you must use a scratch/temp directory (e.g. for `--dry-run` comparisons), pass `--base <current-base>` explicitly — preset codes do not encode the base.
